To all whom it may concern: a

Be it known that I, PETER C. LIEBER, a citizen of the United States, anda resident of Indianapolis, county of Marion, and State of Indiana, haveinvented a certain new and usefulBottle-Capping Machine; and I do herebydeclare that the following is a full clear, and exact descriptionthereof, reference being had to the accompanying draw ings, in whichlike letters refer tolike parts.

This invention relates to bottle capping machines for securing andclenching caps to bottles.

The particular feature of this invention consists of means associatedwith the plunger of the bottle cappingdevice for marking the cap of thebottle or otherwise aliixing to it some indicating mark.

This is accomplished by means of a peculiarly designed die on the end ofthe head of the plunger which will engage the metal cap and stamp animpression thereon. The object of identifying the cap of the bottle bysome peculiar mark is to enable a particular bottle capping machineplunger to be identified as the plunger which capped a particular seriesof bottles. Where certain bottles are poorly cappedso that the contentsof the bottles are liable to be damaged, it has, heretofore, beennecessary to examine all plungers or machines to discover which one isimproperly capping the bottles, while by means of this invention thedefective plungeior machine may be readily identified.

The bottle capping machine shown herein is the same as that shown in myPatent No. 1,170,241 of February 1, 1916. However it should beunderstood that this invention is not limited to any particular kind ofbottle capping machines.

The full nature of the invention will be understood from theaccompanying drawings and the following description and claims.

Figure 1 is an elevation of a bottle and the upper part of the bottlesupport and a central vertical section through the crowning head. Fig. 2is a perspective View of the plunger and plunger head showing theindicating means thereon. Figs. 3, 4, nd 5, are plan views of the capsof bottles after having been capped by three separate capping plungers.Fig. 6 is a detail elevation, partly in section, of a bottle cappingmachine,

showing thereon. H

In the drawings there is a bottle 10 for which a support 11 isprovided,.the upper. end of the bottle projecting into the rigid.crowning head,

tapering throat 12 of the plate. 13. As shown in Fig. 1, the bottle isin position to have a crown. 14 applied thereto, the :bottlesupport l1and crownin head being relatively movable as is usual in this class ofmachines, as will be readily understood'b-y those skilled in the art.Aswill be seen from the drawing the spring encompassing sleeve on theplunger is in engagement with and stopped by the plug 19 to positivelylimit the upward movement of the plunger at the instant that the throat12 of the capping plate 13 limits the upward movement of the cap'andmouth of the bottle 10. Within the casing15 extending upward fromsaid head plate there is a cone trally located plunger 16. Said plungerhas a shoulder near its lower endbelow which ra contracted portion orhead 23 of the plunger projects through a vertical opening concentricwith the throat 12, but of smaller diameter than said throat, as shown.Above the shoulder 17 a spiral spring 18 acts downward, said springsurrounding the plunger and engaging the lug 19 which screws into theupper end of t e casing 15. Therefore, said plug 19 is verticallyadjustable and by it the tension of the spring 18 may be regulated andthe upward movement stopped.

A sleeve or barrel 21 surrounds the spring 18 and lies between it andthe casing 15 and rests upon the lower shoulder 17 of the plunger butstops at a point somewhat below the plug 19 near the upper end of theplunger so as to permit ample compression of the spring. A look nut 22is screwed on the plug 19. The casing 15 and screw plug 19 are arrangedso that the plunger will have only a slight movement and the upwardmovement is yieldingly limited by cooperation of the spring and the plug19.

As the throat and plunger wear, the wear plurality. of capping plungersworking surface of said head there is adie 24 which may be in the formof a letter or number or any other identifying mark. The

'die 'is adapted to mark or impress on the crown the figure or designthereof as shown in Figs. 3, 4 and 5.

In this manner the capping machine whose head is provided with theletter A will impress the mark 25 on the crown 14 so that all bottleshaving crowns with this mark thereon may be identified as having beencrowned by the cappin plunger or machine with the letter A. Li ewise allbottles having themark 125 on the crown 11a may be identified as beingcapped or crowned by the plunger or machine having that particular die.And likewise the bottles having themark 225 on the crown 214. Therefore,as represented in the drawings shown herein, three difierent crowningplungers have capped'the bottles with the crowns, 14, 1-14:,an'd'214. Ifone of these crowns is defective it will beevident that the cappingplunger having that particular die on its head will be the one which isout of order and it may therefore, be readily traced and repaired. Y

In Fig. 6 the material portion of a bottle capping machine is shown,having in it a plurality of plungers 15. There is shown the hopper 30,the upper portion being partly broken away. 31 is the main shaftrevolving the crowning head, and 32 is a casing surrounding thevertically movable bottle supports 11.

The invention claimed is:

1. In bottle capping apparatus, a plural-ity of plungers for cappingbottles, and

means on the capping head of each plunger for making an identifying markon the caps operated on by such plunger, the identifying means on thevarious plungers being diflerent from each other.

2. A bottle capping machine including plungers for capping bottles, andmeans on the capping head of each plunger for making an identifying markon the caps operated on by such plunger, the identifying means on thevarious plungers being different from each other.

3. A bottle capping machine including a plurality of plungers forcapping bottles, and acapping head on each plunger having a speciallyshaped die on the capping face thereof for engaging and forcing inwardparts of the cap marking each cap for identifying the plunger headoperating on a cap, the plunger heads of the various plungers havingdifferent dies upon the capping faces "thereof.

In witness whereof, I have hereunto afiixed my signature.
